So technically that looks alright, but what do you need that for? We
try to not add pinmux values to that table unless they are used
somewhere, especially if there are potential conflicting values: SPI1
on PE is on pinmux 4.
So do you have a board that needs that? Any chance you could upstream
the DT (to the kernel list!) and defconfig for that board? That would
it make it a no-brainer to merge this patch.

Cheers,
Andre
